Women in industry. Gas mask production. Don't let their youth and good looks deceive you, these two young workers are actually full-fledged government inspectors who are employed in a converted Midwest vacuum cleaner plant to test gas masks. Every one of the hundreds of rubber masks that move along the assembly belt each day must be thoroughly tested by young women inspectors who put the masks through many different tests.
